Invitae | RCV001229482 | SCV001401927 | pathogenic | LAMA2-related muscular dystrophy | 2022-10-28 | criteria provided, single submitter | clinical testing | Disruption of this splice site has been observed in individuals with congenital muscular dystrophy (PMID: 24611677; Invitae). For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 956639). This variant is not present in population databases (gnomAD no frequency). This sequence change affects a donor splice site in intron 43 of the LAMA2 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in LAMA2 are known to be pathogenic (PMID: 18700894, 32904964). |
